PKACTICAL FLY-FISHER. 23 



found beneath the stones close to the river's edge, from about the 20th of 

 May, or later, according to the season ; and continue in season about ten 

 days. An imitation of so large a fly can scarcely be expected to kill 

 except in a wind, or late in the evening ; nevertheless I can safely 

 recommend the above imitation to the notice of the scientific angler.
